Paper Abstract

Photonic networks using Optical Burst Switching (OBS) emerged as an attractive choice for building the next generation Photonic Internet. In burst switched photonic networks, contentions caused by multiple bursts intending to use the same wavelength of the same link at the same time, remarkably increase burst dropping probability and degrade network throughput. As efficient contention resolution methods, the previously presented deflection routing and priority-based wavelength assignment (PWA) work individually but are not compatible with each other. It is therefore desirable to combine these two methods together to make further performance improvement. In this work, we revamped PWA to support deflection routing and show the improved performance of deflection routing-compatible PWA through simulation results.
